The Challenge

The Bihar household survey on out-of-school children was one of the largest education data collection exercises in the state, generating nearly 18 lakh paper records. The critical challenges included:

• Massive Scale: 17,81,120 household survey forms needed to be digitized within a tight 3-month timeline, requiring industrial-scale data processing capabilities
• Data Quality Assurance: The paper forms contained handwritten entries in Hindi across multiple fields, requiring meticulous data cleaning and validation to achieve the mandated 99% accuracy threshold
• Data Security: The records contained sensitive personal information about children and families, demanding strict security protocols during handling, processing, and storage
• Complex Data Structure: Each household form contained multiple data fields including demographic information, child details, school enrollment status, reasons for being out of school, and geographic identifiers
• Logistical Complexity: Physical forms were spread across 38 districts and needed to be collected, transported, processed, and securely stored
• Database Integration: The digitized data needed to be formatted and submitted in a MySQL database compatible with the OOSC monitoring application

Velocity’s Solution

Scope of Work

• Chain of Custody: Documented tracking of every physical form from collection to archival
• Audit Trail: Complete log of all data entry and modification activities

Data Submission:
– MySQL Database: Final dataset formatted and submitted in MySQL database format compatible with the OOSC monitoring platform

• Data Dictionary: Comprehensive documentation of all fields, codes, and validation rules
• Quality Reports: Detailed accuracy and quality metrics for each district batch
• Physical Form Archival: Systematic archival and secure return of all physical forms post-digitization

Technology Stack

• Data Entry Software: Custom-built data entry application with field-level validation
• Database: MySQL
• Quality Assurance: Automated comparison tools for double-entry verification
• Security: Encrypted storage, access control systems, audit logging
• Reporting: Automated progress and quality dashboards

Implementation Approach

Given the tight 3-month deadline and massive volume, Velocity executed a highly structured and parallelized approach:

1. Mobilization & Setup (Week 1-2): Established the data entry center, procured hardware, developed the custom data entry application with built-in validation rules, and recruited and trained 200+ operators. Created detailed standard operating procedures (SOPs) for every stage of the process.

2. Form Collection & Preparation (Week 2-4): Coordinated with district offices across all 38 districts for systematic collection and transport of physical forms. Implemented form sorting, batching, and pre-processing including cleaning of damaged or unclear forms.

3. High-Volume Data Entry (Week 3-10): Executed parallel data entry operations across multiple shifts, processing approximately 25,000-30,000 forms per day. Implemented real-time progress tracking dashboards for UNICEF oversight.

4. Quality Assurance (Continuous): Ran continuous quality checks throughout the data entry process. Double-entry verification with automated discrepancy flagging. Daily quality audits on random samples with immediate corrective action.

5. Validation & Submission (Week 10-12): Final database validation, cross-referencing with district-level totals, generation of quality reports, and submission of the complete MySQL database to UNICEF and the Government of Bihar.

6. Archival & Closure (Week 12-13): Secure archival of physical forms, data backup on encrypted media, project closure documentation, and handover of all deliverables.
